Abstract

The research of pineapple utilization as raw materials of bioethanol production using simultaneous saccharification and fermentation (SSF) method has been done. The purpose of this research was to increase the utilization of pineapple as raw material for bioethanol also to obtain the effect of microbial species used and the length of fermentation on the yield of bioethanol. The treatments conducted were species of microbe and the length of fermentation. The results showed that the treatment of multiple microbial cultures of Aspergillus niger, Saccharomyces cerevisiae, and Zymomonas mobilis (1:1:1) with 24-hour long fermentation produce ethanol yield and the optimal concentration of 50,680 ml/kg and 6.335%.

Abstract

Coastal areas of West Kalimantan province are rich with seaweed. To increase its economic value, seaweed could be used as primary materials for organic fertilizer production. This research was conducted to find the optimum combination of seaweeds used for organic fertilizer production using Brassica rapa as test plant on alluvial soils. Most dominant seaweeds found were used for biofertilizer production. Three types of seaweeds used were brown (Phaeophyceae), red (Rhodophyceae), and green (Chlorophyceae). Formulations used were 1:1:1, 1:1:2, 1:2:1, and 2:1:1. The formulation that met the biofertilizer quality conformance was applied on alluvial soils using Brassica rapa as a test plant. Result showed that 2:1:1 and 1:2:1 ratio of brown-red-green seaweed is the best formulation based on most growth parameters observed on Brassica rapa.

Abstract

Cellulase is an important enzyme for industry which can be obtained from cheap tropical agrowastes such as durian peel. West Kalimantan, in particular Pontianak city produces tons of durian peel waste during harvest season each year. This study used durian peel waste as substrates and A. niger to produce cellulase, The aim of this study is to determine the optimum incubation time in producing cellulase under solid state fermentation. Different incubation time (48, 72, 96, 120 and 144 hours) were applied for the production of cellulase. The optimum cellulase production was 120 hours of incubation, giving  protein content of 0.3960% and enzyme activity of 1,069.01 ppm, respectively.

Abstract

The research on The Application of Effervescent Technology of Aloe vera as Functional Drink has been done. The objectives were to obtain effrvescent tablet prefered by the panelist as well as nutritious as aloe vera-based functional food also to obtain appropriate formula resulting good quality of effervescent tablet. Formulation of effervescent tablet with treatments of maltodextrin concentration were done. The result showed that the best formulas of aloe vera effervescent tablet were aloe vera concentration 33%, maltodextrin 7,5%, acid-karbonat total 43%, sorbitol 5%, sukralose 3 % and Polyethylenglicol 8000 %.

Abstract

Aloe vera dodol is a traditional food of West Kalimantan that has short shelf life because of its microbial activity. Antimicrobial edible packaging could be used to maintain the quality of packaged food product actively.The purpose of this study is to prolong the shelf life of food products using antimicrobial edible packaging from durian peel and basil (Ocimum sanctum L.) essential oil. The research was conducted through 4 phases,i.e. the extraction of pectin from durian peel, basil essential oil distillation, Aspergillus flavus inhibition assay, and antimicrobial edible coating production incorporated with Ocimum sanctum L. essential oil. The results showed that pectin extracted from durian peel at pH 4.5 could give yield of 5.9% with a clear coat (Colourless).The concentration of Ocimum sanctum L. essential oil by 0.6% could inhibit the growth of Aspergillus flavus and prolong the shelf life when applied as an antimicrobial ingredient in edible coating.

Abstract

Soybean (Glycine max) has high levels of protein. Furthermore, it also contains raffinose and stachyose, which in high amounts can lead to flatulence. It is known that Rhizopus oryzae could reduce the levels of stachyose and raffinose in soybean flour processing. Lactobacillus plantarum also could reduce stachyose levels on the processing of yoghurt from soybean.  Therefore the aim of this study was to determine the reduction of raffinose and stachyose on soybean fermentation using R. oryzae and L. plantarum isolates. The study was conducted by using combination of R. oryzae and L. plantarum isolates in soybean fermentation process in different length of time. The levels of raffinose and stachyose on fermented soybean products then tested. The results of this study showed that fermentation using R. oryzae single isolates for 2 days (R2L0) can produce soybean flour with low levels of raffinose and stachyose.  The products also have good color and smell.

Abstract

Most mosquito repellent lotions available on the market today contain the active ingredient diethyltoluamide (DEET) which is very harmful to the skin. Natural mosquito repellent research using various essential oils (geranium oil, lemon oil, citronella oil and lavender oil) as the active ingredient and the addition of aloe vera gel as a moisturizer has been done on a laboratory scale. The purpose of this study was to compare the protection ability of the mosquito repellent plants in Indonesia. The results showed that geranium oil, lemongrass oil, lavender oil and lemon oil could act as mosquito repellent. Best lotion formula all containing 15% essential oils have the effectiveness above 50% until the sixth hour were geranium oil, citronella oil and lavender oil while lemon oil only giving effectiveness above 50% until the second hour.

Abstract

Corn starch-based films are inherently brittle and lack the necessary mechanical integrity for conventional packaging. However, the incorporation of additives can potentially improve the mechanical properties and processability of starch films. In this work sunflower oil (SO) and vitamin E (d-alpha-tocopherol) at three levels each (0.05%, 0.1% and 0.15% (w/vtotal)) and (0.18%, 0.36% and 0.54% (w/vtotal)) were incorporated into corn starch films using a solution casting method to improve the mechanical and water vapour transmission rate (WVTR) properties. The addition of SO and vitamin E increased elongation at break of starch-based film while decreased tensile strength and WVTR of starch-based film. The best edible film obtained on addition of sunflower oil concentration of 0.15% and 0.54%, vitamin E with a value of 0.121 mm thickness, tensile strength of 65.38 kg/cm2, elongation at break 14.17% and WVTR 1144 g/m2 24 hours.
